I just bought an 850 from a friend of mine. He's had it for about 5 years with no issues but it stopped running about six months ago. Because he has several other tractors and i had asked if he would sell one he decided to not mess with it and I got it. It turned out to be a bad key switch but it wasn't getting fuel past the sediment bowl. I pulled it off and found it full of grey goop that looked like anti seize compound. I cleaned it out and it fired up but as I have ran it this past week I can see tiny amounts of it building up in the bowl again. Any ideas what it is?
